I'm rather fond of standard Orange Pekoe, as well as Earl Grey. Green Tea is OK hot, but it seems like every variant of cold green tea on the market has this nasty Brisk-like aftertaste that I can't stand. As for how I take my tea, if it's Orange Pekoe, 2 sugars & milk. If it's Earl Grey, just 2 sugars.

Also, for the record, Thai Tea is ridiculously awesome, and Vanilla Chai is pretty good cold.
